I have solved the problem myself. I had only loaded the source code file to my web space. I also needed to load the folder containing the image files to the web space. See http://www.batmatica.talktalk.net/htm
I have uploaded a HTML file created in MS Word to my webspace only to find that the images and coloured background have been blocked / removed when I download it into the browser, either IE or Google Chrome. The same thing happens when using Windows 7 File Manager to upload the HTML file. Any suggestions how to prevent it or any suggestions as to an alternative file format.
